Abstract: Method for the digital run-length coding with redundance reduction for the transmission of binary-coded picture information, whereby short code words are assigned to run lengths which occur often, and long code words are assigned to rare run lengths and whereby, from a given run length on, a prefix word for the differentiation of code words of the shorter run-lengths is assigned to the run-lengths, as well as a code word following the prefix word and stating the respective run-lengths as a binary number. Black and white run-lengths which are transmitted by a code word are associated with different code words, depending on how often they occur. The given run-length, from which the coding is to be done with the help of a prefix word, is different for black and white run-lengths.
